LOS ANGELES — Carmelo Anthony is informing those close to him that he will not sign a contract extension if he is traded to the Nets, according to a person aware of Anthony’s preference.

The decision is not surprising, considering the Knicks have long been Anthony’s desired destination. It could also prove meaningless if the Denver Nuggets bypass Anthony’s desire and trade him to the Nets anyway. he would then be confronted with the same choice: sign a three-year, $65 million contract extension or risk losing millions in a re-engineered labor agreement.

But the Nets are unlikely to agree to trade for Anthony without the a.ssurance that he would sign an extension. On Saturday, a spokeswoman for Mikhail D. Prokhorov, the Nets’ majority owner, said that he had no plans to meet with Anthony while in Los Angeles for the All-Star Game, according to The a.ssociated Press.

“Mikhail has not met with and has no plans to meet with Carmelo Anthony,” the spokeswoman, Ellen Pinchuk, said in the statement.

The Nuggets offered Anthony the extension over the summer when news of his discontent began to percolate. The league’s trade deadline is Thursday, and Anthony said he hoped to reach a resolution by the end of All-Star weekend on Sunday.

“Throughout this whole situation, the only thing I can control is signing that extension with the Denver Nuggets,” Anthony said on Friday. “As far as anything else, I can’t control that.”

The Record of North Jersey reported Friday that the Nets and the Nuggets had agreed on a deal, pending Anthony’s agreement on an extension. In the deal, the Nets would acquire Anthony, Chauncey Billups, Shelden Williams, Melvin Ely and Renaldo Balkman in a package built around Derrick Favors, Devin Harris and four first-round draft picks.

At the very least, the Nets have probably raised the costs of what the Knicks were willing to trade for Anthony. A Knicks official confirmed that James L. Dolan, the Madison Square Garden chairman, met with Anthony here Thursday night. The meeting was first reported by The Daily News.

According to a team executive involved in the talks, the Knicks increased their offer to the Nuggets on Friday. The proposed package included Danilo Gallinari, Raymond Felton and Wilson Chandler, in addition to Eddy Curry’s expiring contract and possibly a first-round draft pick, for Anthony and Billups.

i knew this was going to happen. all these player trades and draft picks dont mean s**t to melo. he wants to be a knick. if i was the knicks i would give them one player/Curry and 1st round draft pick.

If im denver I keep him then. Call his bluff. As much as he wants to be a knick he aint gonna do it for 30 million left on the table. Im sick of these players trying to dictate trades to where they want
